SPECIFICATION 'forming part of Letters Patent No. 635,630, dated October 24, 1899. Application filed July 25,1899. Serial No. 725,092. (No model.)

To @ZZ whoml t may concern:

Be it known that l, EDWARD D. YATEs, residing at Franklin, in the county of Venango and State of Pennsylvania,have invented certain new and useful Improvements in Oil- Tell Pumping-Rigs, of which the following is a specication. v

This invention relates to improvements in well pumping-rigs, and more particularly to that portion of the rig where the pump-actuated rods are attached to the power-shaft; and it primarily has for its purpose the simplifying of the adjustment and connection of the pump-actuated rods to the power-shaft; the adding of strength to said parts where most desired, and decreasing the friction to the minimum.

In its more specific nature this invention seeks to improve the construction of the rig mechanism disclosed in-my Patent No. 593,626, dated November 16, 1897. In my aforesaid patent the power-shaft has its crank portions made non-circular to receive a sectional sleeve having two or more vertical exterior bearings, a horizontal bearing intermediate the vertical bearing portions, and upper and lower horizontal bearings, the sectional actuatingdisk, also forming a part of the said patented construction, which is mounted upon the horizontal and vertical bearings of the shaftsleeve, the said disk having a series of alternately radially disposed dovetailed sockets, a bolt-aperture in each socket, and a bolt-aperture at a point intermediate the inner end of each pair of sockets, said sockets being arranged to receive the dovetailed sockets of the pump-rods that are made secure to the disk by bolts passing through the rods and the apertures in thesaid disk.

While I have found my patented construction aforesaid entirely practical, yet experience has demonstrated the results as not being all that is desired, and my present improvements are intended to add greatly to the value of my former mechanism and render the operation of my complete rig the more effective, economical, and convenient.

With these objects in View my present invention comprehends generally sectional sleeves adapted to engage with the non-circular portions of the crank-shaft and each sleeve formed with upper and lower horizontal bearings and clear of intermediate bearings, and sectional bearing-boxes adapted to fit upon the said sleeves, each box engaging with and being mounted on its corresponding sleeve, with its upper and lower ends to engage with the upper and lower horizontal sleeve-bearings, said bearing-boxes being of two like-constructed parts having a plurality of segmental radially-extended flanges disposed in different horizontal planes, the several flanges of each section overlapping each other, whereby to provide more space for securing the rods than can be obtained with an ordinary single disk member and leaving the iianges in a more useful condition, as well as making the entire box of great strength and durability.

In its subordinate features this invention consists in certain details of construction and peculiar combination of parts, all of which will be hereinafter fully described, and further pointed out in the appended claims, reference being had to the accompanying drawings, in which- Figure 1 is a perspective View of my improved pumping-rig. Fig. 2 is a horizontal section on the line 2 2 of Fig. 3. Fig. 3 is a vertical section on the line 3 3 of Fig. 2. Fig. 4 is a perspective view of a bearing-box and sleeve detached. Fig. 5 is a detail view of the two sections that form the bearing-boxes disconnected from each other, and Fig. 6 is a side elevation of one of the crank-axle sleeve members.

In the accompanying drawings, 1 indicates the rig frame or support, which may be of any approved construction; but on the score of economy of manufacture, strength, and convenience in setting up I pre-fer to construct said frame 1 as shown in the accompanying drawings. The power-shaft in the construction shown has open crank portions 2a 2b, projected approximately in diagrammatically opposite directions, and in the said drawings one of the crank portions 2b is shown disposed above the cross-head 1a of the supportingframe 1, while the other crank portion 2a is located between the master or drive gear 3 and-the cross-head la, as clearly shown in Fig. 1, by reference to which it will also be seen that the gear 3 meshes with a bevel-gear la on the power-shaft 4, having the drive-pulley 1b, which is driven in any well-known manner.

IOC

The crank portions of the shaft in the present form are made non-circular, as shown, and upon each of the said crank portions is mounted a sleeve 7, formed of two sections having internal bearing-faces to snugly fit the shaft and held from turning thereon, and each section 7 has on the upper and lower ends a semicircular flange 7e, the iianges of the two sections when joined forming the upper and lower horizontal bearing members for a purpose presently explained.

So far as described, it will be seen that each crank-shaft portion has asupplemental sectional bearing that can be readily applied thereto or removed therefrom, as desired.

Referring now more particularly to Figs. 2 to 5, the construction of one of the bearingboxes or pump-rod-attaching hubs will be readily seen, the peculiar construction of whicluper se, and its combination with the crankaxle -bearing sleeve and crank-axle forms the essential feature of my present invention.

The hub or box bearing (indicated by S) consists of two half-sections 8n 8, constructed alike and when joined the two sections form a hub adapted to snugly engage and rotate upon the sleeve 7, said hub being of a height corresponding to the length of the flat bearing-surfaces of the sleeve 7, and to minimize the friction the upper face of the lower horizontal bearing-fiange of the sleeve 7 has a ball-race 7X, in which are held the bearingballs 9, the upper sides of which engage the races 8 in the under side of the hub 8, as clearlyshown in Fig. 3, and while I have not so illustrated the same it is obvious a ball-bearing may be provided for the upper face of the said hub S. Each hub-section Sa has a semicircular bearing-groove whereby to provide for a free rotation upon the crank-axle sleeve when the several parts are properly adjusted, as best illustrated in Fig; l. On the outer face of each h ub-section 8a is integrally formed a plurality of annular segmental flanges, two being shown and designated, those on one section by d and those on the other section by a Z1', and each section 8L has laterallyprojected verticall y-extendin g fianges 8d, that receive the fastener-bolts l0, which secure the two sections together. The upper iiange a or a of each section begins at the boltflange 8 at one side of the said section and extends annularly three-fourths, more or less, the distance between the end flanges 8, while the lower flange l or h begins at the opposite flange 8 (meaning the one adjacent the end of the flange a or a) and extends a like dis` tance annularly around the section in a direction reverse to that in which the tlange (L or a extends.

IVhile I have shown the flanges a a and Z2 b as extending, say, three-fourths around the hub, such exact length is not absolutely essential, as the flanges may be vof a less length; but I prefer to make them sufciently long,

so that their inner ends will pass each other or lap, as shown in the drawings. By forming the hub with the radial flanges, as described, it is manifest when the two hub-sections are joined the complete hub will have two upper segmental horizontal flanges projected in diametrically opposite directions and two lower horizontal iianges also projected in a diametrically opposite direction to each other, but alternately to that of the upper iangc. This gives the hub, as it were, a continuous annular flange, to which the ends of the pumprods l2 4may be readily secured, and by reason of the fianges overlapping, or, in other words, extending partially over each other, additional rod-securin g surfaces are provided not obtainable in the disk connection-such, for example, as in myother patent before referred to. )ach hub-flange has a series of perforations 13 for the pivot-bolts that secure the bifurcated or strap ends of the rods l2, as shown.

So far as described it will be readily apparent that by having the flanges overlapping in the center of the hubthat is, at a point at right a-ngles to the meeting edges ofthe two sections-serves to spread the extra strength that they are intended to give the hub, and yet keep the flanges close enough together, so that both of the said flanges can be used at a point where they overlap whenever a very heavy line of rods are to be connected, a contingency constantly made necessary where there are many wells and heavy lines are run out to pull wheels, thus providing a means for attaching the rods to the power-shaft, in itself of great strength and capable of making fast many and very heavy pump-lines.

By providing a hub having iianges, as described and shown, places the extra weight at the places where all of the strain comes, as well as adding considerable more space for rod connections than a single ange would give it, at the same time giving double strength to the face of the hub and also saving a considerable weight by the flanges not extending around the said hub. Again, by having the two sets of anges in different horizontal planes places the rod-attaching portions in a more useful position, for the reason that the pull strain is thereby the more equalized, as the uphill well-rods can be secured to the upper flanges and the downhill well-rods to the lower fianges, thereby distributing the strain on the hub in such amanner that it will work as easily upon the sleeve 7 as if the pull strain from all directions were in a like horizontal plane.

From the foregoing description, taken in connection with the accompanying drawings, it is thought the complete operation and advantages of my present invention will be understood by those skilled in the art to which it appertains.

The rods can be more conveniently and quickly attached than in the manner shown IOO IIO

Vil

in my other patent, a greater number can be connected to each rig, and more satisfactory results obtained with the simplified construction than is possible by the means shown in my aforesaid other patent. Y

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
